Accuray and Erasmus Medical Center Sign Master Research and Collaboration Agreement

- Partnership Creates Strategic Alliance for Advancement of Research in Radiation Oncology in the Netherlands

SUNNYVALE, California, June 26, 2012 /PRNewswire/ -- Accuray Incorporated (Nasdaq: ARAY), the premier radiation oncology company, announced today the signing of a multi-year master research and collaboration agreement with Erasmus Medical Center (MC), a leading research center in Rotterdam, the Netherlands and the largest of the eight university medical centers in the country. Accuray and Erasmus MC will partner on cutting-edge research in radiation oncology with the goal of advancing treatment technology and providing healthcare professionals with the most effective tools for patient care.

"Erasmus MC has a long history of collaborating with Accuray and we are pleased to continue our partnership to advance radiation oncology," said Professor Peter C. Levendag, M.D., Ph.D., Chairman of the Radiation Oncology Department at Erasmus MC. "Our Center's extensive technical research and clinical experience with the CyberKnife System has helped us see and understand the many benefits that radiosurgery offers to cancer patients. We are pleased to reaffirm our commitment to working together to further validate the science of radiosurgery and clinical applications of the CyberKnife System."

Accuray has been working together with Erasmus MC on research initiatives since the Center installed its first CyberKnife® Robotic Radiosurgery System in 2004, making them the fourth site in the Europe India Middle East and Africa (EIMEA) region to install a CyberKnife System at that time. To date, Erasmus MC has treated more than 1,000 patients with the CyberKnife System, performed a substantial amount of clinical research on the use of the CyberKnife System, and authored more than 20 technical and clinical publications in peer-reviewed journals and several book chapters. The Center has used novel research methods to evaluate the performance of the CyberKnife System, including an assessment of the impact of intra-fraction patient motion on clinical tracking accuracy, clinical tracking accuracy of lung treatments using the Synchrony® Respiratory Tracking System, dose calculation accuracy assessments, and methods for reducing treatment time. Currently, the Center is evaluating hypothetical path sets and assessing the InTempo™ Adaptive Imaging System, which enhances the CyberKnife System's ability to continually track and correct for motion of the prostate during treatment.

"As one of the world's foremost academic oncology research centers, Erasmus MC is an important partner for us in advancing the use of the CyberKnife System," said Euan S. Thomson, Ph.D., Accuray president and chief executive officer. "Our collaboration will support the growing body of clinical evidence demonstrating the efficacy and benefits of the CyberKnife System and help us further expand, refine and customize cancer patient treatment. With the support of partners like Erasmus MC, Accuray is poised to lead the charge toward truly personalized radiation oncology."

In the last quarter, Accuray announced two additional research and collaboration agreements including a multi-year master research and collaboration agreement with the University of Heidelberg and the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ), both luminary research institutions located in Heidelberg, Germany.
